Question

使用 spring boot 应用程序作为后端的 Angular 应用程序在 localhost 上工作正常，但是当我尝试部署时，出现以下部署失败错误。我坚持这个问题。我尝试了很多解决方案，但没有任何效果。这是我添加的 pakcage.json，其中提到的 server.js 还添加了 heroku-postbuild。 package.json

下面是 server.js 文件，它负责端口和所有 Server.js 代码

//Install express server
const express = require('express');
const path = require('path');

const app = express();

// Serve only the static files form the dist directory
app.use(express.static('./dist/info-trace'));

app.get('/*', (req, res) =>
    res.sendFile('index.html', {root: 'dist/info-trace/'}),
);

// Start the app by listening on the default Heroku port
app.listen(process.env.PORT || 3000, function(){
  console.log("Express server listening on port %d in %s mode", this.address().port, app.settings.env);
});

下面是heroku日志上的日志错误 heroku 上的错误日志

如果是，这是配置问题，那么如何解决。

angular 应用程序在本地工作但未在 Heroku 上部署失败
